Dispensing valve



March 4, 1941. G. O. MATTER DISPENSING VALVE Filed March 22, 1959 Ill/IA O INVENTOR Patented Mar. 4, 1941 UNITED STATES PATENT OFFICE 7 Claims.

My invention relates to dispensing valves and in particular to pressure controlled dispensing valves.

An object of this invention is to provide means whereby the dispensing of a liquid is actuated and controlled by pressure.

Further objects and advantages of the invention will appear in and from the following specification considered in connection with the accompanying drawing, which are for purpose of illustration and not intended as a definition of the invention, the invention being defined in the appended claims.

Referring to the drawing, in which like characters of reference indicate corresponding parts throughout the several views:

Fig. I is a vertical section of the dispensing valve, shown in connection with a liquid supply pipe, with its operating parts in position as when the pressure is relieved in the supply pipe.

Fig. II is a view'similar to Fig. I, with the operating parts in position as when pressure in supply pipe is sufficient to force the valve seat part way.

Fig. III is a view similar to Fig. II, with the operating parts in position as when pressure in supply pipe is sufllcient to force liquid past the valve seat as shown.

Fig. IV is a view taken on line IVIV of Fig. III.

Fig. V is similar to Fig. I, showing the same principle, a moving valve seat, but of slightly difierent construction.

Fig. VI is a top plan view of Fig. V.

As shown in the drawing a supply pipe I has one or more outlets or faucets, notshown, and

conveys liquid, by pressure into supply chamber 2 and, against the movable valve seat member 3 and when no outlet or faucet in the supply pipe is open, thereby retaining the pressure in the supply pipe. the operating parts are normally in the position as shown in Fig. 11, the valve 4 contacts its seat 5 in the member 3 and the valve 6, which is operatively connected to valve 4, contacts its seat I thereby shutting on communication from dispensing chamber 8 to outlet 9 When an outlet or faucet leading from the supply pipe is opened the operating parts of the dispensing valve are as shown in Fig. I and Fig. V, the pressure being relieved, the seat member 3, which is of a resilient material as shown in Figs. I, II and III or by the action of a spring I0 as shown in Fig. V, rises, thereby lifting valve 4 which lifts valve 6 from its seat 1, permitting the liquid in dispensing chamber 8 to pass through outlet 9.

When the outlet or faucet is again closed and the pressure is retained in the supply pipe I, the operating parts are first as shown in Fig. III, the valve 6 being in contact with its seat 1, the valve 4 is stopped in its downward movement and the pressure continues to force the seat 5 from the valve 4 thereby allowing liquid to pass into the dispensing chamber 8 until the pressure in dispensing chamber 8 becomes sufiicient to overcome the pressure on the other side of the member 3 at which time the valve seat 5 contacts its valve 4 and the operating parts resume the position as shown in Fig. II and remain in this position until the pressure in the supply pipe is relieved by opening an outlet or faucet.

In Fig. V the valve 6 is shown directly connected to valve 4 by stem II which actuates valve 6 by any variation in pressure on the member 3 and as shown in Figs. I, II and III the valve 6 is connected to valve 4 as by the nut I2 on the stem l3 of the valve 6 and the stem i4 with its head l5 loosely mounted within the nut i2 which allows a slight variation in the pressure on the member 3 without actuating the valve 6.

What I claim is:

1. A dispenser consisting of a supply chamber and a dispensing chamber, a movable member between the two said chambers, .an inlet valve and an outlet valvefor said dispensing chamber, said inlet valve adapted to allow communication through said movable member, said inlet valve being controlled by pressure within said supply chamber and said outlet valve being controlled by movement of said inlet valve.

2. A dispenser consisting of a supply chamber and a dispensing chamber, a movable member between the two said chambers, an inlet valve and an outlet valve for said dispensing chamber, said outlet valve being actuated by movement of said inlet valve, said inlet valve allowing communication from said supply chamber to said dispensing chamber through said movable member, a seat for said inlet valve, said seat supported by said movable member and movable therewith, said movable member actuated in one direction by pressure within the said supply chamber and in the opposite direction by resilient means.

3. A dispenser consisting of a supply chamber and a dispensing chamber, a movable member between the two said chambers, an inlet valve and an outlet valve for said dispensing chamber, said inlet valve allowing communication through said movable member from said supply chamber to said dispensing chamber, a seat for said inlet valve, said seat supported by said movable member and movable therewith, said movable member actuated in one direction by pressure within the said supply chamber and in the opposite direction by resilient means, said outlet valve operatively connected to said inlet valve, said movable member effective to close said outlet valve and to open said inlet valve by applied pressure within the said supply chamber, said movable member efiective to close said inlet valve by said resilient means and by applied pressure within the said dispensing chamber, said movable member effective to open said outlet valve by said resilient means and by release ofpressure within the said supply chamber.

4. A dispenser comprising a supply chambsi' and a dispensing chamber, a resilient divisional wall between the two said chambers, an inlet valve and an outlet valve for said dispensing chamber, said valves being connected by a common valve stem, said inlet valve being situated in said divisional wall, said inlet valve being controlled by pressure within said supply chamber and said outlet valve being controlled by movement of said inlet valve.

5. A dispenser comprising a supply chamber in open communication with fluid supply means, a dispensing chamber, a resilient wall separating said chambers, a normally closed valve in said wall, a normally open outlet valve for said dispensing chamber, a common valve stem for the valves restricting them to concurrent longitudinal movement, the said valves and the said wall being so constructed and arranged that upon yielding of the wall the outlet valve is moved to close its opening and upon further movement of the wall the valve seat in the wall opens away from. the valve.

6. A dispenser comprising a supply chamber and a dispensing chamber, a resilient divisional wail therebetween, inlet and outlet valve means for s1 :pensing chamber, said inlet valve be wall, a valve stem common to boths spacing them apart, with the inlet valve Y ally closed and the outlet valve normally open, said spacing being of such amount that upon yielding of the wall due to pressure the outlet valve approaches and closes its seat and upon further yielding the inlet valve is opened.

'7. A dispenser comprising a supply chamber and a dispensing chamber, a pressure sensitive divisional wall between the two said chambers, an opening through said wall, a valve adapted to control communication through said opening, an outlet valve for said dispensing chamber, a common valve stem connecting the valves, said firs named valve being actuated by movement of said wall and said outlet valve being controlled by movement of said first named valve.
